TIRE-TOOL.

Specification of Letters Patent.

Patented Oct. 31, 1911.

To all whom it may concern:

Be it known that I, JAMES L. BUTLER, itizen of the United States,residing at Akron, in the county of Summit and State of Ohio, haveinvented certain new and useful Improvements in Tire-Tools, of which thefollowing is a specification.

This invention relates to a tire attaching and compressing tool incontradistinction to the usual tools for replacing the tire casing overpneumatic tubes.

In the accompanying drawings, Figure 1 is a cross section of a wheeltire, rim and felly with the parts of the tire partially mounted and aside elevation of the tool and means for forcing said parts into workingposition on the tire rim. Fig. 2 is a side elevation and Fig. 3 a view.from the right thereof on a reduced scale of the tool alone;

Fig. 4 is a perspective view of the chain portion of the device. Fig. 5is a plan view of Fig. 2, with the jaw in place.

The invention herein is designed for especial use with a tire of my owninvention and which comprises a compressible tire core O adapted to beused as a substitute for the usual pneumatic tube and is inclosed by theusual outer casing C. The rim It also is of a well known type withinwardly curved side edges or flanges 2 and 3 respectively to engageover the respective beads or enlargements 4 and 5 of the casing. Thecore O however is of an original construction which I have worked outfor wheel tires generally and which is fully described and claimed in acompanion application, Ser. No. 618,676. It suffices therefore to sayhere that the said core is an embodiment of a homogeneous material ormaterials capable of being more or less compressed and resilient, undercompression, especially, but also of a springy or cushioning quality orcharacter inherently. However, it is with the compression of the saidcore that we have to deal in this instance so as to place the casingthereon, and the tool shown is designed for this purpose along with thefastening of the casing beneath or within the flanges of the rim. Ofcourse the said casing itself is the immediate medium whereby thecompression of the core is effected as it envelops the same all aroundand applies the force exerted thereon through the tool as is obvious.

Now, referring to the tool as an article of manufacture, sale and use,the same consists of a main lever A and an auxiliary lever B pivotallymounted on said main lever at 6 near their working ends. Other parts arethe chains D and the connecting piece J, referred to hereinafter as thejaw adapted to force the casing down into engagement with the rim R.

The operation by which the casing is fastened over the cover isprogressive from a starting point anywhere about the tire, and havingmade engagement of the casing beneath the flange 3 of the rim at a givenpoint the casing is held there while further engagement is madeimmediately next thereto as the tool is moved along and so on step bystep until the casing is engaged beneath the rim all around and the coreis incidentally compressed.

In detail the member A of the tool has a bifurcated head between thesides of which the lever B is pivoted, and on the outside of which atboth sides there are lugs 12 with open slots between for engagement ofthe chains D as shown. The end projections of said head indicated by ithave circular recesses (Z in their lower end portions serving asbearings for the jaw J, rounded on its back to rest in said bearingswhen the parts are assembled in working relation. Otherwise the saidchains and jaw are separate from the said levers A and B except as theyengage.in lugs 12 for work.

The lever B has a projection or jaw 7 curved as seen in Fig. 1 andadapted to bear against the otherwise free edge portion of the casingand guide or force it inward behind fiange 3 of the rim while the mainlever is bearing down on jaw J and forcing the casing downward. In thisoperation the chains have first been engaged at one end within the lugs12 and then brought around the rim and tire from within so as to get thejaw J around the outside and into position to be set beneath theextremity of the main lever into recesses (Z. Now, assuming that thechains have been taken up as much as needed the device is in position todo the work. This is accomplished by lifting up on main lever A anddrawing back on lever B more or less, thus suiting both actions to boththe compressing and guiding effects desired. As this proceeds the jaw Jturns on its bearings all until it lies practically fiat against thecasing at last and the ends of the chain connected therewith changerelation in like manner but the recesses (Z are deep enough to confinethe jaw J however severe the pull or strain.

What I claim is:

1. A tool for compressing and attaching wheel tires comprising a mainlever and an auxiliary lever pivoted thereon and having a guiding jaw,and chains adapted to be drawn about the tire and operatively engaged attheir ends with the said main lever.

2. A tool as described comprising a main lever having a head with openslots at its sides and chains removably engaged in said slots andprovided with a cross piece at the other end adapted to be operativelyengaged by the extremity of said lever.

3. A tire attaching tool comprising a main and an auxiliary leverpivotally united, said main lever having a head with recesses in itsextremity and opposite open slots in its sides, and two compressingchains having a jaw member connecting their ends and adapted to beengaged by said recesses.

4. A tool for placing tire casings 011 wheels comprising a main leverhaving a head and two chains operatively connected therewith, and a jawto engage the bead 011 the tire in working engagement with the head ofsaid lever.

5. A tool. to attach a tire casing 011 a rim over a compressible corecomprising a main lever and a guide lever pivoted thereon and adapted todirect the beaded edge of the tire casing to locked position on the rim,said main lever having a head with lateral projections at its sides andcurved recesses in its end, in combination with a jaw adapted to beoperatively engaged in said recesses and flexible members fixed on saidjaw and adapted to be locked in said lateral projection on the head.

6. A tire attaching tool consisting of a main lever and a guide leverfor the edge of the tire pivoted therein, in combination with a separatejaw and flexible members connected with the ends thereof and adapted toengage about the tire, said main lever having a seat for said jaw andconstructed at its sides to temporarily secure said flexible membersthereon.

In testimony whereof I aflix my signature in presence of two witnesses.
